MACHINE FOR SHAPING BUTTONS.

SPECIFICATION forming part Of Letters Patent No. 311,700, dated February31, 1885.

Application filed May ti, 1884. (No model.) Patented in Austria-Hungary1\'o"en1ber 10, 182, No. 32,153 and No. 45,293, and in Germany October15, 1883, No. U 200.

To aZZ whom it may concern.-

Be it known that I, EMIL WEYERBUSOI-I, of the firm of Carl Weyerbusch &(10., of the town ofElberfeld, Rlienish Prussia, Germany, have inventeda new and useful Improvement in Machines for Shaping Buttons, (for whichI have obtained patents in Germany, No. U 200, dated (temporary) October15, 1883; in Vienna, Austria, No. 32,753, November 10, 1882, andin'Pesth, Hungary, No. 45,298, No vember 10, 1882,) which I calltreble-acting button-revolver lathes, of which the following is a full,clear, and exact description.

A good lathe for turning and boring buttons of ivory-nut-, bone, orivory, and similar materials must answer the following require inents:First, it must finish the button out of the rough without requiring thatthe material be reset or taken out of the lathe before the button hasgot its proper shape; second, the acting toolsthe cutters must notsuffer much; third, they must act most exactly and without stoppages,fourth, the lathe must be able to turn out a great deal of work of thevery best finish; fifth, the lathe must be so constructed that it willnot require skilled workmen, and that any laborer can work it. In orderto fulfill these requirements I have constructed the machine describedhereinafter, and shown inthe annexed drawings,of which- Figure 1 gives alongitudinal elevation; Fig. 2, a plan; Fig. 3, a front view seen fromthe left side of Fig. 1; Fig. 1, a front view seen from right side ofFig. 1. Figs. 5, 6, 7, and 8 are detailed views of the tongs arrangementfor holding the button while its back side is shaped. Fig. 9 is ahorizontal section on the line Vll Vlll of Fig. 12. Fig. 10 is averticallongitudinal section on line I ll of Fig. 2. Fig. 11 isavertical transverse section on broken line 111 IV of Fig. 2. 12 is avertical transverse section on line V VI of Fig. 2. Fig. 13 is avertical transverse section 011 line XI XII of Fig. 2. Fig. 14 is avertical longitudinal section on line IX X of Fig. 13. Fig. 15 is avertical transverse section on line XIII XIV of 2. Fig. 16 is a frontelevation.

A are the standards on which the machine is erected. B is the bed,carrying the spindles, head-stocks, and the other working parts of thelathe. The lathe is driven from a suitable head-gear by means of thecone-pulleys C.

On the shaft of the latter is fixed the pinion D,which gears into themain spur-wheel E on the shaft G. This shalt G can be set in and out ofgear by means of the lever H, which allows the pinion D to be pushed outof gear with the wheel E. The lathe spindles J, K, andL, which arejonrnaled in the head-stocks P Q R, are driven from a head-gear by meansof the fast and loose pulleys M N O. The head-stocks Q and R are carrieddirect upon the bed 13 of the lathe,in which they can slide in alongitudinal direction. (See Figs. 1, 4, 3, 11,and 10.) The headstock P,however, finds its bed in the headstock Q.upon which it can slideforward and backward independently of the movement of Q. The forward andbackward motion is given to these head-stocks P Q R by thecam-dru ms S TU. respectively, on the shaft G, these head-stocks being connected withthe cam-drums by means of the arms or pins V V X. at the lower end ofeach of which there is a little roller, which projects into the grooveof the respective cams. Thus by turning the cams the pins V \V X mustfollow the rise and fall of the grooves in the cam-dru ms, and shift thehead-stocks forward and backward or hold them in one place, according tothe direction of the grooves in respect to the direction of the axis ofthe shaft Nearly in the middle of the lathe-bed B is fixed anotherheadstock, Y, which carries 1V hereby it will be observed that thespindles J and K shape the front side of the button, whereas the spindleL gives the shape or form to the back side, a special contrivance beingadopted for this purpose.

Let me now de-' scribe the revolver disk and the manner of fastening thematerial to be worked in it, and' On this pin, in front of the disk 0,is fitted the revolver disk Z, so that it can be turned round. Thefixing of the button material in the revolver disk Z is done in thefollowing manner: In the back side of disk Z are cut the six T-shapedslots 6 to e. Into these slots are fitted the sliding pieces f, whichform claws. These claws are drawn toward the center by the spiralsprings 9, so that if any piece of material is put between the claw ofthe sliding piecef and the edge of the revolver disk it will be heldfast between the two. Suitable recesses are provided for that purpose,in addition, in the edge of the disk and the lower part of the claw, sothat if pressed close together the two recesses form a round hole, It,as can be seen from Figs. 13 and 15. The piece of ivory-nut when it isfirst brought into the lathe being very rough and unequal in shape atthe sides, andthus opposing at times great resistance to the tools andalso when a deep cut is taken, might not be held fast enough by thesprings 9 only. The claws are further pressed down for the two firstcuts by the strong springs z, bolted at one end to, the circumference ofthe fast disk 0, and pressing with the free end on the presser-bars k.

From the foregoing it will be seen that the material is properly heldwhen the cutters of the spindles J'and Kare at w0rk,and the working ofthe machine so far is the following: A piece of raw materialivory-nut,bone, &c: is set into the revolver disk at L, the claw f being withdrawnby the hand while the re volver is at rest and the nut put below it.Motion is then given to the disk by the ratchetwheel Z, which is fixedto its front on the pin (2, pawl m, lever n, and rod 0, the latter beingbolted to the oscillating cam;lever p,of peculiar shape. This cam leverhas its fulcrum at q, and itis so shaped that the little roller T, whichis fixed to the disk 8, strikes against it at certain moments, and thusraises it or pushes it downward. The disk 8 is keyed to the shaft G androtates with it in the direction of the arrow. In the position shown inFig. 13 the lever p has just been pulled down, and rod 0, lever n, andpawlm have turned the ratchet-wheel and the revolver disk sixty degrees,or one-sixth of a revolution. The roller 1' leaves the cam-lever nowfree until it reaches the position r. During this time of rest for thelever and revolver disk a new piece of ivory-nut is fixed at L, whilethe tools work at B and (2. As soon as roller r arrives at the position1" it strikes against the cam-lever,raises it in continuing itsrevolution, and the rod 0, lever 11, and pawl m are raised, so that thelatter falls into the next tooth or notch of the ratchet-wheel, ready toturn it another one sixth of a revolution, when the roller 1" comes incontact with the lever 11 in its proper place and at the required fitteddovetail shaped in the back of the disk c, and carries at its bottomside a little roller, V, which stands on the circumference of theeccentric t. This eccentric is keyed fast on the shaft Gand rotates withit. It is so shaped that it raises the sliding pieceu at the propermoment, and by this the press bars k are pressed upward, which are alsofitted on the back of disk 0, and held there and guided by the piece 10and the front side of the headstock Y. Thus the press-bars leave thedisk Z freeto turn when required. They are pressed down by the springst'as soon'as the eccentric it allows it. A special arrangement is alsoprovided to hold the revolver disk securely fast and exactly in theproper place while the tools are at work. For this purpose the revolverdisk Z is provided at its circumference with notches or gaps to, Figs.13 and 15, always between two sliding claws, f, and a lever, 00, with asuitablyshaped finger, x, is pressed against the revolver disk by thespring y, and falls into the gaps when they come in its way. In order torelieve the revolver disk from this hold when it shall turn, a littleroller, z, is fixed to one side of the eccentric t, which on its turnstrikes against the lower inner part of the lever 00 and presses itdown. so that detent 00 gets out of the gap in Z, and this is free torevolve.

It now remains to describe the contrivance provided to hold the buttonwhen it is turned and shaped at the back side by the cutter of thespindle L. This arrangement is shown clearly in Figs. 1 to 8.

It consists of a sort of tongs or nippers, e, which are fixed to thehead-stock Q, and move forward or backward with it, but which at thesame time have also an independent motion from the headstock Q by meansof the cam-drum S. The proper shape having been given to the button bythe cutters ofJ and K, and the revolver having turned the button in thereach of the cutters of L and of the tongs 0, respectively, these movetoward it in advance of the head-stock Q, a greater speed for atimebeing given to them by the relative position of the grooves in thecam-drums S and T, so that the tongs while advancing with the head-stockare, besides, pushed forward by the action of thelever K. The tongs andlever K are held in place and guided by the brackets I andtt. The latterare bolted to the bed of the lathe. Set-screws o serve for adjusting thetongs at the exact place in lateral direction, whereas the verticalset-screws 20, which are worked simultaneously by the hand, andspur-wheels- IlO ' hold fast.

I) serve to adjust them in vertical direction and also to open them moreor less, according to the diameter of the button to be held. \Vhen thetongs are to be bodily raised by the screws ",which are journaled in thebracket K and threaded into thelowerguides, Z, the set-screwot' guide Zmust be loosened and re adjusted to the new position. Vhen the tongs arethus properly located, the movement of the hand-wheel and rod b tendsonly to open and close the tongs by acting on the lower jaw thereof. Thetongs e have their support or turningpoint in block S, so that thespring T tends always to open them at the righthand side of Figs. 1,5,.and 8. Adjustable guide-pieces Z and Z prevent undue separation ofthe tongs, so that the opening be not more nor less than'is required.These guidepieces being fast with the bracket K, it will be understoodthat if the tongs e are pushed by the lever K toward the right-hand sidethe support or turningpoint S" of the tongs will approach Z and Z, andthus the tongs will be opened more. The guide-pieces are, of course, setso that the opening corresponds to the size of the button which thetongs shall If, then, the tongs have advanced sufficiently that they arewithin reach of the button, their movement is stopped by shaping thegroove in the cam-drum S accordingly, and the headstock still moves on,so that the guidepieces Z and Z come to standnearly to the right end ofthe tongs S. It will be seen from Fig. 5 that the upper half of the cutat the back side of the button is performed,

and at the same time the finishing-cut of the front side by the cutterson K, the cutters on J have already been withdrawn according to therelative position of the cam-drum S in regard to the drums T and U, sothat the vibrations caused by the cutters on J in cutting the firstshape out of the rough shall not be trans mitted to the cuttersKandLwhen they make their finishing-cuts, and a thoroughly-clean andwell-finished button will be obtained. The button so finished completelymust now be taken out of the lathe. This is done automaticallyin thefollowing manner: The head stock goes back in advance of the tongs, sothese, coming free of the inclined plane S', are opened by the pressureof the spring T, and the button is free to fall out; but to prevent itsfalling toward the tongs there is a plate, 'I, fixed between the tongsto the bracket a on the bed B. This, therefore, stands quite immovable,and if the button should happen to remain between the tongs it will bepushed out of them when the button on its way back with the tongs andthe headstock reaches the edge of the plate T.

In accordance with the above, I claim as my invention- The combination,with the headstock Q, fitted to slide upon the bed B of a buttonmakingmachine,and the button-holding tongs e, fitted to slide longitudinallyin the headstock of the plate T, located between the tongs and fixed tothe machine relative to the motion of the tongs, substantially asdescribed, whereby a button will be knocked out of the tongs in theirretreating motion.

The foregoing specification of my improved machine for turning buttons,called treble acting buttonrevolver lathe, signed by me this 22d day ofJanuary, 188%.
